Like in Brink, vast parts, or most parts of the world are now underwater, only few places are still ''dry''.
And just like there, there's a floating city, in the middle of the sea, called Golden City.
There's also kind of a police force like the security, and rich and noble people live there, just like on the ark.
The comic centers around that city and a rich well known guy called Harris Banks.
But i wont tell you more about it, or i'd only spoil it. I guess you can get the comic in french or german,
but im not sure about the english/american part. It's at least worth looking at it.
